90% of industry caused air pollution comes from 5% of plants

Rural Blog - A small minority of industrial facilities are responsible for the majority of air pollution generated by the industry, says a study published in Environmental Research Letters.
 
The study, which examined industrial emissions at about 16,000 industrial facilities—excluding power plants—"found that '90 percent of toxic concentration present in the study area is generated by only 809 (about 5 percent) of facilities.' The highest polluting facilities were also more likely to be located in proximity to poor and minority neighborhoods."
